Java in a Nutshell, 5th Edition [Electronic resources] نسخه متنی

This interface represents a notation declared
in the DTD of an XML document. In XML notations are used to specify
the format of an unparsed entity or to formally declare a processing
instruction target.

The getNodeName( ) method of the
Node interface returns the name of the notation.
getSystemId( ) and getPublicId(
) return the system identifier and the public identifier
specified in the notation declaration. The getNotations(
) method of the DocumentType interface
returns a NamedNodeMap of
Notation objects declared in the DTD and provides
a way to look up Notation objects by notation
name.

Because notations appear in the DTD and not the document itself,
Notation nodes are never part of the document
tree, and the getParentNode( ) method always
returns null. Similarly, since XML notation
declarations never have any content, a Notation
node never has children and getChildNodes( )
always returns null. Notation objects are
read-only and cannot be modified in any way.
